Coolio's,
There is a 57 x 57 c-c Rotrax that is listed on Oz ebay which is a touch too big for me (otherwise I wouldn't be telling you about it). The listing for Australia only and unfortunately it's not close to me but if someone on the list has to have it, is patient and understands that it's not easy I am happy to help take delivery and then ship it onwards.
Needs paint, chrome .. the works but I think these are very cool. I don't know the seller but s/he has a few interesting bikes and frames listed.
ciao,
